I am creating an SKScene with two buttons.import UIKit
import SpriteKit
class IntroScene: SKScene {
override func didMove(to view: SKView) {
// BUTTON PLAY GAME
let btnPlay = BtnPlay(normalTexture: defaultBtnTexture,
selectedTexture: selectedBtnTexture,
disabledTexture: nil)
btnPlay.size = CGSize(width: 250, height: 75)
btnPlay.position = CGPoint(x: frame.midX,y: frame.height/3*1)
btnPlay.name = "btnPlay"
btnPlay.setButtonAction(target: self, triggerEvent: .TouchUpInside, action: #selector(IntroScene.goToGameScene))
print("BUTTON PLAY FRAME 1 ",btnPlay.frame)
addChild(btnPlay)
// BUTTON 'FIND PLAYERS'
let btnFindPlayers = BtnFindPlayers(normalTexture: defaultBtnTexture,
selectedTexture: selectedBtnTexture,
disabledTexture: nil)
btnFindPlayers.size = CGSize(width: 250, height: 75)
btnFindPlayers.position = CGPoint(x: self.frame.midX,y: self.frame.height/3*2)
btnFindPlayers.name = "btnFindPlayers"
btnFindPlayers.setButtonAction(target: self, triggerEvent: .TouchUpInside, action: #selector(IntroScene.goToConnectVC))
print("BUTTON FIND FRAME 1 ",btnFindPlayers.frame)
addChild(btnFindPlayers)
}
@objc func goToGameScene() {
print("Go to Game Scene")
}
@objc func goToConnectVC() {
print("Go to Connect VC")
}
}This is the custom class for one of the buttons. The other class uses similar methods:import SpriteKit
class BtnPlay: SKSpriteNode {
enum BtnPlayType: Int {
case TouchUpInside = 1,TouchDown, TouchUp
}
var disabledTexture: SKTexture?
var defaultTexture: SKTexture
var selectedTexture: SKTexture
var label: SKLabelNode
var isEnabled: Bool = true {
didSet {
if disabledTexture != nil {
texture = isEnabled ? defaultTexture : disabledTexture
}
}
}
var isSelected: Bool = false {
didSet {
texture = isSelected ? selectedTexture : defaultTexture
}
}
required init(coder: NSCoder) {
fatalError("NSCoding not supported")
}
init(normalTexture defaultTexture: SKTexture!, selectedTexture:SKTexture!, disabledTexture: SKTexture?) {
self.defaultTexture = defaultTexture
self.selectedTexture = selectedTexture
self.disabledTexture = disabledTexture
self.label = SKLabelNode(fontNamed: "Helvetica");
self.label.text = "PLAY"
super.init(texture: defaultTexture, color: UIColor.white, size: defaultTexture.size())
isUserInteractionEnabled = true
self.label.verticalAlignmentMode = SKLabelVerticalAlignmentMode.center;
self.label.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.center;
addChild(self.label)
let bugFixLayerNode = SKSpriteNode(texture: nil, color: UIColor.clear, size: defaultTexture.size())
bugFixLayerNode.position = self.position
addChild(bugFixLayerNode)
}
var actionTouchUpInside: Selector?
var actionTouchUp: Selector?
var actionTouchDown: Selector?
weak var targetTouchUpInside: AnyObject?
weak var targetTouchUp: AnyObject?
weak var targetTouchDown: AnyObject?
func setButtonAction(target: AnyObject, triggerEvent event:BtnPlayType, action:Selector) {
switch (event) {
case .TouchUpInside:
targetTouchUpInside = target
actionTouchUpInside = action
case .TouchDown:
targetTouchDown = target
actionTouchDown = action
case .TouchUp:
targetTouchUp = target
actionTouchUp = action
}
}
func setButtonLabel(title: NSString, font: String, fontSize: CGFloat) {
self.label.text = title as String
self.label.fontSize = fontSize
self.label.fontName = font
}
override func touchesBegan(_ touches: Set, with event: UIEvent?) {
if !isEnabled { return }
isSelected = true
if (targetTouchDown != nil && targetTouchDown!.responds(to: actionTouchDown)) {
UIApplication.shared.sendAction(actionTouchDown!, to: targetTouchDown, from: self, for: nil)
}
}
override func touchesMoved(_ touches: Set, with event: UIEvent?) {
if !isEnabled { return }
let touch: AnyObject! = touches.first
let touchLocation = touch.location(in: parent!)
if (frame.contains(touchLocation)) {
isSelected = true
} else {
isSelected = false
}
}
override func touchesEnded(_ touches: Set, with event: UIEvent?) {
if !isEnabled { return }
isSelected = false
if (targetTouchUpInside != nil && targetTouchUpInside!.responds(to: actionTouchUpInside!)) {
let touch: AnyObject! = touches.first
let touchLocation = touch.location(in: parent!)
if (frame.contains(touchLocation)) {
UIApplication.shared.sendAction(actionTouchUpInside!, to: targetTouchUpInside, from: self, for: nil)
}
print("BUTTON PLAY FRAME ",frame)
print("BUTTON PLAY TOUCHES ",touchLocation)
}
if (targetTouchUp != nil && targetTouchUp!.responds(to: actionTouchUp!)) {
UIApplication.shared.sendAction(actionTouchUp!, to: targetTouchUp, from: self, for: nil)
}
}
}The scene and the buttons are created just fine. Button "Find Players" is created on top. The problem is that when I tap on the lower button ("Play"), nothing happens. The culprit is tapping on the screen. Whenever I tap somewhere on the screen, except for the lowest part of it, the upper button gets selected. So, if I tap on the lower button, I still see on the console:BUTTON FIND FRAME (387.0, 474.5, 250.0, 75.0)
BUTTON FIND TOUCHES (409.139404296875, 563.622131347656)Looks like the frame of the upper button is much greater than the button itself and superimposes the lower button not letting me tap on it.Have no idea why this is happening.I would greatly appreciate if someone can help.
